Looks like no one looks at those threads on the "Important ECU Threads"

I'm tyring to figure out who has a good formula to get accurate logs when logging with my AEM? I can't get it to be accurate at all.. I followed the directions on the HOW TO but no good results as far as logging.

Either I can get Idle/Cruise logs to be very close if not on the dot... The minute I WOT the gauge and Logs aren't NEARLY close.

Sorry In Advance if there's an answer to this but I personally cant find it.

YES i know I can just buy a DB9 Cable and whatnot.... I would PREFER to not have to use another USB slot.

 

I've had a hell of a time getting mine close and switched to a db9. Now I'm nervous using it analog again in my vi-pec which uses wbo2 for fuel corrections.

I think the power and grounding sources have to do with the inaccuracies. Where are you sourcing power and ground and what's your formula?

 

I had issues getting mine to work at first and hen figured out my gauge was switched to the 0-1 volt output setting not 0-5. Once switched correctly, it worked really well and very close readings from analog output to ecu. Pretty sure my formula is the same as posted in the how to threads.

 

Acutally... I leave this thread for future questioners..... I got so fed up looking at 50 million threads I couldn't get a TRue Reading...

I took my Serial from my X and now logging the 9 how I should of LMAO. Sorry Guys But Everything I did was based on How-Tos. I either got good Idle Reads but once you got WWOT it didn't go much on the Rich side....
